SHORT TERM /THROUGH MONDAY NIGHT/

Issued at 147 PM CST Sun Jan 25 2026

The DVN CWA becoming increasingly under the influence of tightening LLVL pressure gradient between a 1040 MB high pressure center acrs the western Dakotas, and the headline making cyclone rolling up the eastern OH RVR Valley and Appalachia. Resultant brisk north sfc wind of 10-20 MPH will maintain into Monday morning. This flow combined with it's cold air advection(CAA) the reason for the already issued Cold Weather Advisory tonight into Monday morning with widespread values of 20 to near 30 below zero. A -22C H85 MB cold pool progged to be right over the area at 12z Monday. Most ambient low temps ranging in the single digits below zero. Cloud cover may be an issue for portions of the area, but the stubborn stratocu covering the eastern half of the finally feeling the effects of back cloud layer flow and thus starting to retreat back east and edge erode. But other stratocu acrs SD/NE/southeast MN may try to drift this way overnight so there may be some patchy cloud cover at times making for sfc temp variations.

Monday...After a cold start to the day, broad northwesterlies acrs much of the upper mid half of the CONUS will look to shuttle a clipper wave out of Canada and into the heart of the GRT LKS through Tuesday. This feature to start inducing an increasing low to mid level vertical flow profile, with H85 MB jet looking to increase to 40-50 KTS from the west by late in the day. This will bring about strong low to mid level WAA from the west and flush out the cold pool. Sfc temps will steadily rise during the afternoon and into the evening/overnight periods, with 12 hour highs probably occurring at around 00z Tue. Southwesterly sfc winds of 15 to 25 MPH will put quite an edge to any warming ambient temps. Temps to continue to hold up in the upper single digits to mid teens into Tue morning, before a cold front sweeps through the region as Tuesday progresses. The clipper system not to have much of a moisture draw and most of it's associated precip will stay just off to the north and northeast of the DVN CWA, or at worst a few flurries skirt acrs the northeastern portion of the CWA Late Monday night into Tue morning.

LONG TERM /TUESDAY THROUGH SATURDAY/

Issued at 147 PM CST Sun Jan 25 2026

Tuesday to trend to a blustery northwest wind day with CAA getting traction as the day moves along...but not after mixing produces high temps in the teens to near 20. Ongoing/blocked broad northwesterlies will continue to bring down re-enforicng bouts of cold air, and several weak clippers undulating down acrs much of the northeast half of the CONUS. Too hard to tell at this point if one such wave or two may skirt the region close enough for some nuisance light snow chances a few times this upcoming week, and now it's looking like it may be mainly dry for the home team if the latest ensembles are correct. The past few runs of the ECMWF have lost the Wednesday clipper acrs the local area.

As for temps, below normal trends look to continue in this type of pattern for at least the next week. Several nights this week we may near Advisory level cold, especially north of the Hwy 30 corridor. This while ice continues to thicken on area rivers and lakes.

AVIATION /18Z TAFS THROUGH 18Z MONDAY/

Issued at 1125 AM CST Sun Jan 25 2026

An area of MVFR ceilings from Wisconsin through northwest Illinois and far eastern Iowa is sluggish to fade. Late morning satellite trends indicate this could linger to 20Z-21Z before it does so at MLI and DBQ. There is a low chance of some very fine flurries with this. Otherwise, a north wind sustained 11-15 kt with sporadic higher gusts of 17-21 kt will be the rule through this evening. Winds back westerly by Monday morning with VFR conditions during the day Monday with high confidence.
